e1“With increased plant density, DM accumulation per area increased logarithmically, the HI decreased according to a cubic curve, and GY per area increased quadratically”
e5“The experiment was conducted for 3 yr, with drip irrigation and plastic mulching, at the 71 Group and Qitai Farms located in Xinjiang, China”
e6“Two modern cultivars, ZhengDan958 and ZhongDan909, were planted at 12 densities ranging from 1.5 to 18 plants m −2”

Other claims from this paper (12)
- Association Harvest index decreased with increasing plant density in maize, following a cubic curve.
- Association Grain yield per area increased quadratically with plant density in maize.
- Observation The optimum plant density for maize was 10.57 plants m -2.
- Association In Range I (4.7 or fewer plants m -2), DM per area, HI and GY per area were significantly affected by density.
- Association In Range II (4.7-8.3 plants m -2), HI was unaffected by density.
- Association In Range II (4.7-8.3 plants m -2), DM per area and GY per area were significantly affected by density.
- Association In Range III (8.3-10.75 plants m -2), GY per area was unaffected by density.
- Association In Range III (8.3-10.75 plants m -2), DM per area and HI were significantly affected by density.
- Association In Range IV (10.7 or more plants m -2), DM per area was unaffected by density.
- Association In Range IV (10.7 or more plants m -2), HI and GY per area were significantly affected by density.
- Observation Range II is a density-independent range for maize.
- Observation Range III is a GY-stable range for maize.
